Specification of Letters Patent.
Patented Mar. 12, 1912.
Application filed March 2, 1911. Serial No. 611,903.
To all whom it may concern:
Be it known that I, TnoMAs S. WVA'rsON, a citizen of the United States, residing in Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented new and useful Improvements in Elevating, Transporting, and Discharging Apparatus, of which the following is a description, reference being had to the accompanying draw ings, which are a part of this specification.
This invention relates to improvements in elevating, transporting and discharging ap paratus for handling coal or other mater alv It is one of the objects of this invention to provide an elevating, transporting and discharging apparatus in which the con struction is simplified by having the main hoisting motor adapted to also open and close the material holding receptacle.
A further object of the invention is to provide an apparatus of the class described in which the independent control of a motor on the carriage serves to draw in the SlilCh of one of the operating cables and also on pedites the opening of the material recep tacle.
A further object of the invention is to provide an apparatus of the class described in which the counterweight ordinarily used may be dispensed with, if desired, without materially affecting the operation of the apparatus.
A further object of the invention is to provide an elevating, transporting and discharging apparatus which is adapted for use in connection with long and short hauls and in which the traversing motor may be placed on a fixed support in a short haul apparatus and in a long haul apparatus the traversing motor may be placed on the carriage and the carriage cable be dispensed with.
A further object of the invention is to provide an apparatus of the class described in which the counterweight is raised or lowered to raise or lower the receptacle by means of an independent motor located at a fixed point.
With the above, and other objects in view, the invention consists of the elevating, transporting and discharging apparatus as set forth in the claims, and all equivalents thereof.
In the accompanying drawings in which the same reference characters indicate the same parts in all of the views: Figure 1 is a side view of a portion of a tower provided with the improved elevating, transporting and discharging apparatus, parts brolccii away; Fig. 9 is a diagrammatic perspective view of the cable system thereof and also showing the carriage, the motors, the counterweight and the pulleys; Fig. 3 is a top view of the carriage modified to the extent of having the motors mounted thereon; Fig. 4 is a side view thereof; and Fig. 5 is a detail view of the electric controller handle for controlling the modified form of carriage.
Referring to the drawings the numeral 8 indicates a portion of a tower which is mounted on wheels 9 adapted to travel on the track 10 in the usual manner. The tower is provided with a boom 11,, and tracks 12 carried by said tower and boom support a carriage 13 which is adapted to travel back and forth thereon. A hoisting drum 141 and a receptacle opening and closing drum 15, respectively, are mounted on the carriage and have connected thereto a drum rope or cable 16 which is wound therearound and depends downwardly therefrom. The depending ends 17 and 18 of the cable are connected, respectively, to the receptacle 19 and to the opening and closing mechanism 20 of said receptacle. This cable 16 extends from the hoisting drum 141 in the direction of the line of travel of the carriage to and around a guide pulley 21, upwardly and around and depending in a loop 22 between pulleys 23 and returning in the direction of travel over the carriage and around a pulley 2L located at the free end of the boom and from thence returning to the receptacle opening and closing druni 15 and terminating in the end 18 before described. A pulley 25 engaged by the loop 22 of the cable 16 is journalcd in a strap 26 which carries a counterweight 27 in the lower portion thereof. A counterweight operating cable 28, the upper end of which is connected to the upper end of the counterweight strap, extends upwardly therefrom between the looped portion of the cable 16 and around a pulley 2.) and down to the drum of the counterweight motor 30 located on the tower. The cable is wound around the said drum and depends downwardly therefrom and around the guide pulleys 31 and up to and is connected to the lower end of the counterweight strap 26 so that when said motor is rotated, the counterweight will be raised or lowered with the loop 22 of the cable 16 and cause the raising or lowering of the receptacle 19. An electric brake 32 having a geared connection with the hoisting drum 14 is adapted to retard the speed of rotation of the drum in order to open or close the jaws of the receptacle when desired. In this short haul apparatus the motor 34 for traversing the carriage back and forth along the track is located on the tower and a traversing rope or cable 35 wound on the drum of said motor extends in the direction of travel of the carriage and the opposite ends of the cable are connected to opposite ends of the carriage. The cable is supported on suitable pulleys 36 located at opposite ends of the trackway and on the upper intermediate pulley 37 for supporting the portion of the cable which extends over the carriage. The motors on the tower are controlled by the electric controllers 37 while the retarding brake on the carriage is controlled by the push button contact forming part of one of the handles of said controllers.
The operation of the apparatus thus far described is as follows: Assuming that the parts are in the positions shown and it 1s desired to charge the receptacle and. convey the material to the opposite end of the track and discharge it, the counterweight cable motor is rotated to lift the counterweight which movement will shorten the loop of the drum cable and lower the material bucket or receptacle. At the same time the push button is pressed to cause the retarding brake to slightly retard the rotation of the hoisting drum which will cause the jaws of the bucket to open while the bucket is dropping toward the material. The momentum of the. dropping receptacle will force the jaws thereof deeply into the material so that when the motors are reversed and the retarding brake retards the rotation of the hoisting drum, the opening and closing drum will draw'in its cable at a greater rate of speed and cause the jaws to dig into the material and fill the receptacle and the receptacle will then be elevated to a point adjacent to the carriage by the pull. of both cables. The traversing motor is now started to pull on the traversing cable and pull the carriage to the opposite end of the track, the drum cable being carried along by the carriage and playing freely through the counterweight pulley and the guide pulleys. As-soon as the opposite end of the track is reached, the traversing motor will be stopped and the counterweight cable motor rotated to again. raise the counterweight and lower the bucket and at the same time the retarding brake is operated to re .tard the hoisting drum and the jaws of the bucket will then open and discharge the material.
In the modified form shown in Figs. 3
and 4 the traversing motor 34 is mounted direct-1y on the carriage and the traversing cable 35 is dispensed with. This motor has a geared connection with the carriage wheel shaft 37 for driving the carriage back and forth on the track. In this modified form of apparatus it is desirable to provide means for taking up slack in the opening and closing portion of the cable 16 to prevent whipping of the cable and to accomplish this result a small motor 39 mounted on the carriage and geared to the opening and closing drum 15 is provided for accelerating the speed of rotation of said drum and keeping the cable taut. A cab 40 suspended from the carriage of the modified form of apparatus is adapted to accommodate the electric motor controllers 37, before described, if desired in order to control the motors from said carriage. The acceler ating motor 39 is controlled by a push button connected to one of the controller handles which is similar to the push button sh own for controlling the brake. In the operation of this modified form of apparatus the counterweight cable motor is rotated to raise and lower the receptacle and the retarding motor rotated to control the opening and closing of the jaws of the receptacle in the same manner as before de scribed and the traversing motor on the carriage is rotated to cause the travel of said carriage on the track. In operating the apparatus at a fast rate of speed the tendency of the opening and closing cable to sag and whip is overcome by means of the accelerating motor which is rotated to take up slack and hold the cable taut.
The independent connection of the hoisting motor to the counterweight cable provides a simple construction and relieves the carriage of the weight of the motor and also provides for eliminating the counterweight if desired as it is obvious that the said weight may be dispensed with and the l apparatus will operate in the same manner with the exception that the receptacle will not be counterbalanced and more power will be required to elevate the receptacle.
From the foregoing description it will be seen that the apparatus is very simple in construction and operation and is well adapted to perform the functions desired. The novel arrangement and construction of the parts provides for the location of the smaller motors either on the carriage or on the relatively fixed support and thus adapts the apparatus to a large variety of uses and modifications.
